UNITED STATES Application filed December This invention also consists incertain other features" of. construction and 1n the combination andarrangement of the'several parts, to be hereinafter fully described, il-

lustrated in" the accompanying drawings and specifically pointed out inthe appended claims. i

In describing my invention in detail, reference will be had to theaccompanying drawings wherein. lilce '-cliaracters denote like orcorresponding parts throughout the several views, and in which Figure 1is a. perspective view showing the invention in'use.

Figure 3 is a longitudinal sectional view.

Figure 4 is an end view with the file in' section. 1

- Inrthese views, 1 indicates the body of the fileholder which isprovided with a socket toreceive the'chucks 2 for engaging a filewhichis shown at A, the chucks being contrzlcted. by the sleeve t3.-These parts are of the usual or any desired construction. A handle 4 isrotatably mounted on the shank 5 of the body '1, said handle beingprovided with-a sleeve 6 through which the shank passes, the parts beingheld together by the set screw 7. A collar 8 is 'rotatably mounted .on apart of the body 1 and has a threaded socket 9 therein for receiving thethreaded end i of a weight '10 which tends to hold the collar in acertain position on the body. The collar is held in ad justed positionon the body by the threaded sleeve 11 on the body which clamps thecollar betWeen itself and a part'of the body. A scale 12 is. carried bythe collar and a marker 13 is carried by a part of the body .forpermitting the collar to be adjusted to the desired extent on the body.Then by screwing the sleeve 11 against the collar the I Figure 2 is aplan view of the device.

collar will be held in its adjusted position. This scale and marker-willpermit the parts to be adjusted togive the file the proper position tocut the teeth at the desired pitch. The device is held with the handlein one hand and the fingers of the other hand holding te'tip of .,thefile, The weight 10, will cause the body and the file to move relativelyto the handle until the weight is in its lowest'positioir, which will bethe position for which the fileis set to give the teeth of th-esaw thedesired pitch. Thus with this device all the teeth will be given thesame pitch and they may be given any desired pitch by adjusting theparts of the device accurately and without guessing at the pitc'h.ii IThe weight 10 may be provided with an opehinglO. so that the weight canbe used as a plumb 'bob by attaching a string to it by means of thispassage.

It is-thought fromthe foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionandin the combination and arrangement of the' several parts, providedthat such changes fall within the scope of the appended claims.

What I claim is 1; A filing device comprising a holder, a collarrotatably mounted on a part of the handle, a threaded socketon thecollar, a weight having threaded engagement with the socket, a nutfor'holding the collar in adjusted position on the body, file holdingmeans associated with the body and a handle rotatably connected with thebody.

2. A filing device comprising a handle, a collar rotatably mounted 'on apart of the handle, a threaded socket on the collar, .a weight havingthreaded engagement with the socket, a graduated scale on the exteriorof the collar, a handle 'rotatably connected ture.
